SUGAR-EVAPORATOR.

SPECIFICATION forming part of Letters Patent No. 272,093, dated February13, 1883,

Application filed November 24, 1882.

To all whom it may concern Be it known that we, DAVID SMOUSE, CHARLES W.SMousE, and DAVID H. SMoUsE,

. of Mount Pleasant, in the county of Henry and State of Iowa, haveinvented certain new and useful Improvements in Sugar-Evaporators; andwe do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and-t0 letters of reference markedthereon, which form a part of this specification.

Figure 1 represents a perspective view, looking from above down on thedevice. Fig. 2 is a similar view of the cover. Fig. 3 is an enlargedface and side view of a detail, showing the connection between the panand finisher.

Fig. 4 is a sectional detail View, showing the construction of thekinks. Fig. 5 is a side elevation of one of the receiving-pipes.

This invention relates to improvements in evaporators, more especiallyto those used for sugars and sirups.

The object of the invention is to produce an evaporator which shall beself-skimming, and.

in which the sirup will be thoroughly strained and finished Theinvention consists in a combined evap' orating pan and finisher havingthepeculiarities of construction hereinafter set forth.

In the annexed drawiugs,.the letter A represents the evaporator,consisting of a pan, B, and finisher 0, made separate and unitedtogether at their ends, as shown at a, by the connector I. As indicated,the evaporator is made preferably rectangular, and its corners arestrengthened by the exterior angle-plates or cornerirons, a. The pan Bis formed with an extension, I), at one side, out of line with thefinisher O, as shown. In this extension the pan .is furnished with thethree walls I) b N, the first about on the line of the edge of the finisher, the three forming a receptacle, b, in which is a hole, b The endsof this extension b, outside of the walls b b ,are formed into offsets Dand D, in which are inclined boards or plates, preferably perforated, dd, loosely connected to the tops of the walls b 11 and extending outinto said offsets. At the op- (No model.)

posite side of the pan, in its angles, are placed the corners E, madeangular at the back, so as to fit the angles of the pan, and rounded infront. These corners or blocksE have flanges c at the bottom, forming arecess, c, beneath, and have passages c, which lead through the cornersfrom the top down to the recess. Fitting in said holes are the turned-upends f of the supply or receiving pipes F, which terminate at theirendsf in the pan.

Seated within the pan is the cover Gr, resting against the wall I) atone side and the edge of the pan at the other, and leaving a space ateach end in the pan, outside of the cover, as shown. This cover G islined with metal, and

.consists of a top, 9, side pieces, g g, and sliding jackets g g havinghandles, as shown. The side pieces, 9 g, are provided with grooves g gin which the ends of the jackets fit, and said pieces g g extend beyondthese grooves, the ends atone side resting against the corners E Eandholding the cover in position.

Extending from the pan B, underneath the cover, is the educt-pipe H,which passes into the connector I and leads from the pan to thefinisher. This connectorconsists of two plates of metal, It h, which areplaced on the inner sides of the ends of the pans B G, and they all arebolted together, as indicated in Fig, 3. Through the registering-holesIt in these the educt-pipe H, passes, and is provided with the, cut-off7L2.

Arranged across the bottom of the pan B and finisher O are several lowridges or kinks, K, which divide them into several compartments andstrengthen the bottom. These kinks are made by placing strips of metalis from side to side of the evaporator and then turning the metal bottomL over the upper edge and two sides of the strips and bolting themtogether, all as shown at l lin detail in Fig. 4:.

At one side of the evaporator is placed the tank M, for receiving thejuice before it comes to the pan. This tank has a pair of grooves, m m,on each side, in which are to he fitted the ends of screens or filters NN, thus dividing the tank into two compartments, m m, the latter havinga faucet, m One filter only is employed in use, and when it is cloggedanother is placed in the adjoining set of grooves and the other filterremoved and cleaned.

Only one tank is shown in the drawings, but two are to be employed, oneat each end of the pan; or one large tank may be used with two sets ofscreens, forming three comparments, the middle toreceive the crudesirup, the other two to discharge it into the pan.

This evaporator is placed, as usual, upon the brick arch or frame-work,so as to be heated, the offset b being to one side of the brick-work,and not having any fire under it. The crude juice is poured into thecompartment m ofthe tank M, and, passing through the screen or filter Ninto compartment m is drawn off through the faucet m and passes down thepipe hlvinto the pan 0. As thejuice is discharged at D D, it flows underthe jackets g beneath the cover 9, and by aid. of the interior heat andsliding jackets g 9 a double automatic current is formed, and the screenis carried to D and D, and the pure defecated juice flows through thepipe H into the finisher 0. .As the scum, 850., rises within the panbeneath the cover, it is forced by the current into the ofi'sets D D,and,passing over and up the inclines dd,falls into the receptacle b andis drawn off through the hole D The pure juice flows through theeduct-pipe H into the first division of the finisher, and passes overthe first ridge into the next division, and so on until it passes intothe last and is drawn off at a finished siru p. The pan, as thusconstructethhas a double capacity, and thejuice being admitted at bothends increases the working facility. The cover havingtwojackets,thejuice passes in at both ends and runs rapidly under theinfluence of the heat beneath, and the metal lining keeps the heat in,being practically air -tight.

As thus constructed, the device is adapted to work automatically. Thejuice in the pan is separated from the scum, the latter being forced tothe offsets and the defecated juice passes from under the cover into thefinisher. This makes the evaporator self-skimming, and attention in thisregard is only needed to remove the buckets as often as they becomefilled With the discharged scum. Thejnice is thor-.

oughly defecated, and under the cover is subjected to an intenseheat,which purifies it, and the purer portion passes off below throughthe educt-pipe into the finisher. Herein it is still operated upon, andis graduated off until it comes out at p a finished article.

Having thus described our invention,what we claim is 1. An evaporatorhavingthe offsets D D,inclines d cl, and scum-receptacle b*, as setforth.

2. The evaporator having the corner, E, with passage e, and the pipe F,having the end f in said passage, as set forth.

3. An evaporator having the cover Gr placed in the middle and a spacefor receiving the juice at each end, as set forth;

4. The cover Gr, having sides g g, with grooves g and the slidingjackets g 9 fitting said grooves, as -set forth.

5. The cover G, havingthe sliding jackets g g whereby is formed a doublecurrent, as set forth.

6. The cover G, havinga metallining, as set forth.

7. The pan B, finisher O, and educt-pipe H, in combination with theconnector I and the cover G, the pipe H leading from under the coverinto the finisher O, as set forth.

8. The connector I and pans B O, secured together, in combination withthe educt-pipe H, having the cut-off h, and the cover G, the pipe Hleading from under the cover into the pan 0, as set forth.

9. Thejuice-tank M having the filters N N, as set forth.

10. The evaporator, having the metal corner irons, as set forth.

11. The strips 76, in combination with the continuousbottomL,turnedoverthem,assetforth.

In testimony that we claim the foregoing as our own invention we allaffix our signatures in presence of two witnesses.
